ajax.module: An unknown error has occurred - when someone clicks 'submit' twice or more

I've solved this by disabling the submit button when it's first click and enabling it back again when it has finished the request. i did this in the ajax.js file. I'm attaching a patch, please review and make sure it works.

regards

EDIT: removed as my comment was not related to this patch. Thanks

Patch is dodgy ;D

getting today after recent core and module updates - ajax.module: An unknown error has occurred.

symptom: editing a node and clicking submit button

I have the same issue..

I dynamically load a View with an argument. In this view I use Ajax pager.

When I go to the page 2 (or 3) and submit a Comment it triggers 2 or 3 times the submit form (number of trigger : nbr_page-1)

The first post works but then I have this error and it reload all my views...

Kind regards

Found a solution, using the patch on #3 comment:

I've edited ajax.js located in ajax module folder,

find Drupal.Ajax.go function approx. on line 83 and replace the whole function:

this is the original:

Drupal.Ajax.go = function(formObj, submitter) {
  var submitterVal, submitterName, extraData;
  Drupal.Ajax.invoke('submit', {submitter:submitter});
  submitterVal = submitter.val();
  submitterName = submitter.attr('name');
  submitter.val(Drupal.t('Loading...'));
  extraData = {};
  extraData[submitterName] = submitterVal;
  extraData['drupal_ajax'] = '1';
  formObj.a_ajaxSubmit({    
    extraData : extraData,
    beforeSubmit : function(data) {
      data[data.length] = {
        name : submitterName,
        value : submitterVal
      };
      data[data.length] = {
        name : 'drupal_ajax',
        value : '1'
      };
      return true;
    },
    dataType : 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      window.alert(Drupal.t('ajax.module: An unknown error has occurred.'));
      if (window.console) {
        console.log('error', arguments);
      }
      return true;
    },
    success: function(data){
      submitter.val(submitterVal);
      Drupal.Ajax.response(submitter, formObj, data);
      return true;
    }
  });
  return false;
};

Replace with this one:

Drupal.Ajax.go = function(formObj, submitter) {
  var submitterVal, submitterName, extraData;
  Drupal.Ajax.invoke('submit', {submitter:submitter});
  submitterVal = submitter.val();
  submitterName = submitter.attr('name');
  submitter.val(Drupal.t('Loading...'));
  extraData = {};
  extraData[submitterName] = submitterVal;
  extraData['drupal_ajax'] = '1';
  formObj.a_ajaxSubmit({    
    extraData : extraData,
    beforeSubmit : function(data) {
      data[data.length] = {
        name : submitterName,
        value : submitterVal
      };
      data[data.length] = {
        name : 'drupal_ajax',
        value : '1'
      };
      submitter.attr('disabled', 'disabled');
      return true;
    },
    dataType : 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      window.alert(Drupal.t('ajax.module: An unknown error has occurred.'));
      if (window.console) {
        console.log('error', arguments);
      }
      return true;
    },
    success: function(data){
      submitter.val(submitterVal);
      Drupal.Ajax.response(submitter, formObj, data);
      submitter.removeAttr('disabled');
      return true;
    }
  });
  return false;
};

having the same problem, but cannot be sure it the result of clicking submit twice. is this related to http://drupal.org/node/786502? I'll test the solution in #8 and report back.

hi,

my login - register block is working fine, but when I am trying to add user through admin panel and fill the form when I click on signup, I am getting Ajax.module: An unknown error occurred.
please help

Is there a working patch for this?

I'm getting this behaviour on D6 when submitting a webform form that has a mandatory email address field. This seems to be line 106 in ajax.js.

Maybe it's related to this issue - http://drupal.org/node/786502

dataType : 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      window.alert(Drupal.t('ajax.module: An unknown error has occurred.'));
      if (window.console) {
        console.log('error', arguments);
      }
      return true;
    },

Drupal 6.22
Ajax 6.x-1.15

I always get that message on a node save, but the node always saves correctly, so I just removed the error function for it :D. I have no idea what the problem is :/. My nodes have a lot of processing that takes place. It takes maybe 10 - 15 seconds for a node to save on my site. I'm on the latest D6 (Pressflow) with Ajax Module 6.x-1.x-dev, 2011-Apr-08. I run Open Publish and use the Rubik admin theme.

Fixed thanks to @cluke009's contribution at https://github.com/brendoncrawford/drupal-ajax/pull/2

Guys , i understood where exactly this error is loading from. The ajax error due to parsing error. The function of form_set_ error is working with jquery 1.3 ver .Its doesnot support laest versions .So, W e need o add json_decode function in inc.php which will solve ajax login/register error. If you have more questions , reply on same

nagrgk,
Can you explain exactly what I have to do to add json_decode function inside inc.php?

I have got this problem and I want to solve it!

Thank you
